Functionalities

VECTOR DATA MANAGEMENT:

PhotoSoft has a number of tools for managing vector data. The first group includes the basic operations of vector data:

Creation

Changing

Copy

Move

Rotate

Miror

Array

Scale

Modify element

Break element

Extent

Extent element to intersection

Trim element

Insert vertex

Deletion

Delete part of element

Delete vertex

Specialized operation over vector data:

arched-section

reduction of facilitiy measurements

orthogonal method

When creating and editing geometry it is possible to implement a number of conditions including:

Length condition

Angle condition

Azimuth condition

by setting the value or interactive input using a 2D/3D mouse.

SNAP:

Snap allows you to automatically position the cursor 2D/3D mouse when it comes to the environment of a geometric object.

PhotoSoft has a greater number of options to adjust the snap function.

Snap mode:

Auto snap (on the fly)

Manual snap

2D/3D mod:

2D snap – closeness is checked only by positional coordinates (x, y)

3D snap - works similarly, but takes into account the third, Z coordinates and checks the closeness taking into account all three coordinates.

Geometries with enabled snap:

Key Point Snap - vertex, endpoint, midpoint

Near Point Snap- cursor to "catch" the nearest point of the nearest geometric object.

GEOMETRIC SELECTION:

Geometric selection can be made by 2D or 3D mouse. PhotoSoft respects several parameters that determine the result of selection.

Spatial definition of selection:

Select touch

Select box

Select polygon

Select polyline

Select existing shape - existing geometry – after version 1.0

The parameter which determines the manner in which will be pre-treated with the selected geometry:

New

Add

Subtract

Invert

Parameter which determines the geometry that will be selected according to the spatial relationship with the area selection:

Inside

Intersect

Inside+intersection

SYMBOLOGY:

PhotoSoft representation of geometric objects is done on the basis of display styles. Accordingly, geometry types have four display style and:

Point

Line

Area

Textual

Display of geometric objects may be defined at the feature level and at the level of class attributes feature class. This second method enables the geometry of each single attribute defines the mode.

3D/2D DISPLAY:

PhotoSoft has a two-view, which are optionally included.

3D view is intended for stereoscopic display selected for stereo and vectors. 2D view (top view) shows the vector content. The windows are synchronized so that one view monitor each zoom and pan the other view-a.

DIGITAL TERRAIN MODEL:

One of the main functions of PhotoSoft is the collection and verification of data for digital terrain models (DTM). As part of MapSoft package, Surfing module is for generation and analysis of DMT based on previously collected data. PhotoSoft is used for the collection, storage and visualization of DMT, while the generation of DMT is SurfIng task.

Original data which is generated DTM consists primarily of points, lines and surfaces in addition to 2D coordinates with their height.

PhotoSoft task is divided into two parts:

Collecting source data (scattered points, points on a regular grid, the structural lines of the court)

Visualization derivatives of DMT such as contour lines, triangles of Delaunay triangulation or other DTM data analysis.

Regular network of points (Grid) has served solely as a tool for "guidance" 3D cursor in the measurement points spaced at regular intervals.

There are several more parameters if the parameter type of the original data DTM is Regular network of points. These parameters are not defined at the level of the Grid, but rather at the level of the feature and the class are:

Profile patern

Default height

Starting point of measurements

In order to generate DTM PhotoSoft respects several types of points and lines of which depends model itself.

Types of points to generate a DTM:

Mass points

Spot points

Bottom points

Peak points

Types of lines to generate a DTM:

Slope lines

Breaklines

Waterflow lines

Vododelnice (Ridge lines)

Saddle lines

Generating of DTM can be made at several spatial filter (screen, active model, box, project).
